SEGDNDARY BATTERY.

Patented Sept. 25, 1888,

wi/mana@ of copper ie not easily obtained and menipit lated, end tizio process I ilove described perhops as gooit any for attaining tlie desired end. So, too, I might place phosphate of zine 5 on the zinc element; orli. might piece oxidee oi' either metal upon supporte vof copper or of zinc. In case plain platee or elieets of copper or zine are used there is e -necessary disintegration of the surface to e greater or lees (le plieation ofIinely-divided particles of the sonic material with the metal or elementary snb stance composing the electrodes is simply to afford greater capacity for electro-chemical action.

I do not herein, cleim,in an electric buttery, the combination of e negative elementoJ post tive eloinent, und e diaphragm or septum com' posed of asbeetns, e. sol uble salt'and a silicate; combined together enbsteotielly as deseri bed, ce that forms the subject-metter of :in application filed by me in the United States Potent O-Hice on the 18th (my of- April, 1888, Serial Nhat I cloinnond desire to secure by Lettere Patent,is
